Applied Sciences and the Environment

About this book

This book features the proceedings of the International Conference on Applied Sciences and the Environment (ASE '98). Organised by the Universidad de Cadiz, Spain, and the Wessex Institute of Technology, UK, this meeting also incorporated part of V Jornadas de Medio Ambiente (JORMA V). Bringing together mathematicians, physicists, chemists, environmental scientists and engineers, the conference provided a discussion forum for all scientists working with mathematical models for the environment in different fields and types of applications. They were therefore able to share knowledge and experiences from their separate fields and contribute potential solutions to a wide variety of environmental problems. The 29 papers featured are divided under the following headings: Measurement and Data Analysis; Pollutants and Environmental Chemistry; and Environmental Management and Control.
